Definitions
- This invention relates to a apparatus providing a means of transport for an object and, more particularly, to a jet aircraft engine transport apparatus for transport of jet aircraft engine components.
- Jet aircraft engines are perhaps the most critical assembly of an aircraft wherein the engines must be inspected and maintained to the highest level of repair. Periodically, it is necessary to remove these engines from the wing or fuselage of the aircraft so that the aircraft engine can undergo the necessary repairs.
- the fan section may be removed from the core section either when the entire jet aircraft engine has been removed from the aircraft or some circumstances dictate that only the fan section be removed while the core section remain attached to the aircraft.
- one significant shortfall is that none of the prior art devices provide a complete transport apparatus comprising a group of devices which are compatible with one another such that the major components of the jet aircraft engine may be secured and transported in the desired mode of transport. Furthermore, the prior art does not provide for a transport apparatus which enables aircraft engine components to be transported on differing types of aircraft and wheeled vehicles without having to use a series of complex equipment. Thus, one major advantage of the invention disclosed herein is its ability to accommodate differing aircraft engines for both air and land transport.
- US-A-5383652 discloses a jet aircraft engine transport apparatus for providing multimodes of transport for jet aircraft and including a shipping stand for shipping a jet aircraft engine thereon.
- the shipping stand includes a cradle assembly.
- a fan dolly is provided for transporting a fan section of the jet aircraft engine and includes an attachment assembly mounted on the fan dolly for securing the fan section to the fan dolly.
- the attachment assembly includes at least one load indicating assembly coupled thereto for measuring the load placed by the fan section upon the fan dolly.
- Means are provided for shipping the fan section of the jet engine when loaded on the fan dolly.
- the apparatus operates by aligning the fan dolly with the fan section, then attaching the fan dolly to the fan section and then removing the fan section from the aircraft by pulling the fan section away from the jet engine along the longitudinal axis of the engine using a train assembly.
- a jet aircraft engine transport apparatus for providing multi modes of transport for jet aircraft engines and their components, said transport apparatus comprising a shipping stand for shipping a jet aircraft engine thereon, the shipping stand including a cradle assembly, a fan dolly for transporting a fan section (F) of the jet aircraft engine and operable for precise horizontal displacement of the fan section (F), said fan dolly including an attachment assembly mounted thereon for securing the fan section (F) to said fan dolly, said attachment assembly including at least one load indicating assembly coupled thereto for measuring the load placed by the fan section (F) upon said fan dolly, and means for shipping the fan section (F) of the jet engine loaded thereon, characterized in that the shipping stand is for shipping a jet aircraft mounted thereon in either a truck transport mode or an air transport mode, the shipping stand including at least one spacer that is engaged with said cradle assembly to space the cradle assembly from the shipping stand to select one of said modes, the shipping means comprising a shipping frame for shipping
- a method of removing the fan section (F) of a jet aircraft engine from the aircraft engine having a longitudinal axis comprising the steps of aligning a fan dolly (10) with the fan section (F); attaching the fan dolly to the fan section (F) by means of an attaching assembly (100) including means for measuring the amount of load placed upon the fan dolly by the fan section (F); measuring the load placed on specific locations of the fan dolly by the fan section (F); distributing the load of the fan section (F) on the fan dolly as necessary to provide a smooth removal of the fan section (F) from the aircraft engine; removing the fan section (F) from the aircraft engine by pulling the fan section (F) away from the jet aircraft engine wherein the fan dolly includes a train assembly enabling the fan section (F) to be displaced precisely and horizontally on the fan dolly along the longitudinal axis.
- a fan dolly for transporting a fan section (F) of a jet aircraft engine loaded thereon, said dolly comprising a frame for supporting a fan section (F) mounted thereon; at least one fan support including an attachment assembly for attaching the fan section (F) to said fan dolly, said attachment assembly including means for measuring the amount of load placed upon the fan dolly by a loaded fan section (F), characterized in that at least one rail member is provided having a length and mounted to said frame; said measuring means being selectively positioned on said at least one fan support to measure loads at specific locations on said fan dolly and a train mechanism being mounted on each of said at least one rail member and attached to each of said at least one fan support for enabling said at least one fan support to be selectively displaced along said at least one rail member.
- the fan dolly subcomponent utilizes a novel attachment assembly which measures the load placed on the fan dolly from a loaded fan section and inlet cowl, incorporates a novel train assembly which enables the fan section to be removed from the core section of a jet aircraft engine, and enables the fan section to be directly loaded onto the shipping stand.
- a novel attachment assembly which measures the load placed on the fan dolly from a loaded fan section and inlet cowl
- incorporates a novel train assembly which enables the fan section to be removed from the core section of a jet aircraft engine, and enables the fan section to be directly loaded onto the shipping stand.
- the attachment assembly includes a plurality of load indicating devices, such as dynamometers, which indicate the load placed upon the attachment assembly by a loaded fan section and inlet cowl.
- load indicating devices such as dynamometers
- a cable ratchet assembly is provided to adjust the amount of load placed upon the attachment assembly at specific locations.
- the fan dolly includes a frame assembly which has mounted upon it a pair of train assemblies.
- a plurality of caster assemblies are also mounted to the frame assembly and which provide locomotive capability to the fan dolly.
- Means are provided within the caster assemblies to raise or lower the fan dolly enabling it to cooperate with the shipping stand, shipping frame or particular aircraft from which the fan section is to be removed or onto which it is to be loaded.
- a fan support assembly is mounted on each of the train assemblies which releasably secures the fan section to the fan dolly.
- a traversing assembly of each of the train assemblies enables a loaded fan section to be displaced along the fan dolly in precise horizontal increments so that the fan section may be positioned for removal from the core section of the jet aircraft engine or positioned for loading onto the shipping stand or shipping frame.
- the attachment assemblies and train assemblies can compensate for any vertical deflection of the shipping stand as the fan section and cowl are removed from the core section. That is, as the fan section and inlet cowl are removed from the core section which is still secured to the shipping stand, the shock absorbers of the shipping stand (described below) will have a tendency to deflect to a less loaded condition which in turn will deflect the core section in relation to the fan section. This deflection of the shock absorbers can be compensated for by the attachment assemblies and train assemblies.
- the fan dolly is also compatible with a number of commercial engine shop pedestals so the fan section can be removed from the core section to undergo repairs. Furthermore, the fan dolly of this invention has advantages over prior art devices which utilize conventional cradle and shock absorbing components, and which have inherent deflection problems during engine splitting operations. Also, the fan dolly of this invention enables engine splitting and fan section transport with a minimum of equipment and manpower.
- the shipping stand subcomponent of the transport apparatus utilizes spacer elements which may be positioned in a truck transport mode wherein a plurality of shock absorbers are activated to provide shock absorbing support to a loaded aircraft engine, alternatively, the shipping stand may be positioned in an air transport mode wherein the spacers are stowed and the shock absorbers are deactivated.
- the spacers are positionable in either desired mode by the use of an integral hydraulic system which raises and lowers a cradle assembly which supports the mounted engine.
- the advantage of such a dual mode system is based on the need to transport a jet aircraft engine on land via a wheeled vehicle and/or on the main deck of a Boeing 747 or other jet aircraft for further destinations.
- the shock absorbers are required to provide shock protection to the mounted jet aircraft engine from the impacts associated with road travel. Without such protection, the jet engine could be easily damaged during transport.
- the shock absorbers are not required. This is due to the fact that air transport is a much smoother means of transport wherein the natural flight of the aircraft generally provides adequate shock absorbing protection.
- the shipping stand may be lowered from the truck transport to the air transport mode at an ideal height which enables the jet aircraft engine to be directly loaded through the cargo door while the jet aircraft engine remains secured to the shipping stand.
- the structure of the shipping stand includes a frame assembly including a plurality of frame members which provide adequate support to a cradle assembly which cradles or secures a jet aircraft engine. Mounted to the frame assembly are wheels which enable the shipping stand to be pulled by a vehicle. The plurality of shock absorbers are operatively engaged between the frame assembly and cradle assembly to provide adequate shock protection to the jet aircraft engine when the shipping stand is in the truck transport mode.
- lifting mechanisms are provided to lower or raise the cradle assembly corresponding to the desired mode. In the truck transport mode, the lifting mechanisms raise the cradle assembly to a predetermined height which creates gaps between upper transport flanges and lower transport flanges.
- the lifting mechanisms are deactivated which causes the shock absorbers to bear the weight of the loaded aircraft engine.
- the shipping stand may be placed in the air transport mode. This is achieved by activating the lift mechanisms, removing the spacers between the transport flanges and then lowering the cradle assembly so that the gaps between the transport flanges are eliminated.
- the spacers are stowed on the shipping stand by use of storage support flanges positioned adjacent the transport flanges.
- Each spacer includes indicia which indicates which mode the shipping stand is configured. More specifically, each spacer includes a plurality of mode slots which cooperate with corresponding mode pins formed on the upper and lower transport flanges. The cooperation of the mode slots with the mode pins results in the appropriate indicia appearing on the side of the spacer exposed to viewing. Thus, the indicia serves to ensure that an operator of the shipping stand does not inadvertently place the shipping stand in the inappropriate mode when transporting the jet aircraft engine.
- the shipping stand is described as having particular utility with respect to transport of a Boeing 777 jet aircraft engine by use of a Boeing 747 aircraft, it will be understood that the present invention is intended for many other uses as it is easily adaptable to accommodate the transport of many different types of jet aircraft engines for truck transport and air transport on numerous different types of aircraft.
- the height of the cradle assembly in the truck transport mode and the air transport mode may be altered so that a particular jet aircraft engine may be loaded directly onto a specific type of aircraft.
- the cradle assembly may be raised or lowered in the truck transport mode by altering the specific construction of the frame assembly or cradle assembly.
- any number of different sized spacers may be used to enable a smooth transition from the truck transport mode to the air transport mode and vice versa. Accordingly, the ranges of the lifting mechanisms may also be altered to accommodate the specific height necessary for transition between the two modes.
- the shipping stand just described it is possible to provide a dual mode of transport for a jet aircraft engine loaded thereon.
- the shipping stand therefore enables direct loading of an aircraft engine onto an aircraft by changing the configuration from a truck transport to an air transport mode and, conversely, enables a smooth transition from an air transport mode back to a truck transport mode once the jet aircraft engine has arrived at its destination. Accordingly, the shipping stand prevents having to use complicated winch assemblies or other means to load and unload the jet aircraft engine onto and from the aircraft. Additionally, because of the smooth transition between truck and air transport, the chances of damaging a jet aircraft engine during transport is greatly reduced. Furthermore, the process of transporting a jet aircraft engine can be accomplished in a much more cost effective and efficient manner by utilizing the shipping stand of this invention.
- the fan shipping frame subcomponent of this invention is used when the fan section of a jet aircraft engine needs to be transported by itself.
- the fan section may be loaded directly upon the shipping frame.
- a fan section may be transported in either an upright position, or it may be tilted ninety degrees (90°) so that the fan section is positioned on its end in a horizontal position. Transporting the fan section in the upright mode is acceptable when shipping the fan section by means of, for example, a Boeing 747 jet aircraft or on a truck.
- the fan section of a Boeing 777 aircraft is to be transported, for example, by a C130 cargo aircraft, the fan section must be positioned on its A-flange or end because the rear cargo hatch of the C130 aircraft is too small to accept a vertically positioned Boeing 777 fan section.
- the shipping frame includes a frame assembly for supporting a loaded fan section.
- the fan shipping frame includes a plurality of caster assemblies which provide locomotive capability to the fan shipping frame.
- a plurality of jack mechanisms attached to the frame assembly enable the shipping frame to be positioned at a desirable height so the fan section may be loaded onto the appropriate aircraft or vehicle.
- rail members mounted on the frame assembly are alignable with rail members on the fan dolly so that the fan section may be directly transferred onto the shipping frame.
- a novel platform assembly is deployed enabling the fan section to be tilted without the aid of external equipment.
- a storage container which may receive and store the fan blades of the fan section in either the upright or the tilted mode.
- the storage container includes a plurality of storage cells which have unique curved shapes which match the shape of the fan blades.
- the jet aircraft engine transport apparatus of this invention includes three major subcomponents. Namely, the transport apparatus comprises a fan dolly 10, a shipping stand 210, and a fan shipping frame 310. As illustrated, the fan section F of the jet aircraft engine has been removed from the core section C of the jet aircraft engine. Accordingly, the core section C is shown mounted on the shipping stand 210 while the fan section F is shown mounted upon the fan dolly 10.
- the fan dolly 10 is shown as being coupled to fan shipping frame 310 wherein the fan section F may be directly transferred to the fan shipping frame, as will be further discussed below. Prior to mounting the fan section F onto the shipping frame 310 from the fan dolly 10, the inlet cowl I is removed.
- the fan section F is illustrated as being separated from the core section C in Figures 1 through 4, it will be understood that the fan section F may remain attached to the core section and, therefore, the entire jet aircraft engine may be shipped or transported solely on the shipping stand 210. This configuration of transport is best seen in Figure 13 wherein the core section C is shown as being attached to the fan section F.
- the shipping stand 210 may be aligned with a jet aircraft engine that is still attached to the wing or fuselage of an aircraft or may be aligned with a jet aircraft engine that has already been removed from the aircraft. Once aligned, the inlet cowl, core section C and fan section F or only the core section C of the jet aircraft engine is secured to the shipping stand. If the loaded jet aircraft engine sections are to be transported by ground, the shipping stand is configured in a truck transport mode which provides shock absorbing support to prevent damage to the loaded section(s). If the loaded jet aircraft engine sections are to be transported by air, the shipping stand is configured in an air transport mode wherein the loaded shipping stand may be directly loaded onto an aircraft.
- the fan dolly 10 serves not only to support the fan section F and inlet cowl I, but also to prepare the fan section for loading upon the shipping frame 310.
- the fan dolly 10 of this invention may be aligned for receiving the fan section F of a jet aircraft engine when the jet aircraft engine is either mounted to the aircraft or when the entire jet aircraft engine has been removed from the aircraft. In either instance, once aligned, the fan dolly secures the fan section and enables it to be transported via ground transportation, allows it to be transferred to the shipping frame 310 or received from the shipping stand 210.
- the inlet cowl I Prior to loading the fan section onto the shipping frame, the inlet cowl I is removed and stored at a remote location.
- a pair of rail members on the fan dolly 10 mate with rail members on the shipping frame 310 enabling the fan section F to be directly transferred to the shipping frame without the necessity of external equipment.
- the fan section F may be secured to the shipping frame by means of a template 332 which cooperates with a plurality of holes 109 on the fan section F.
- Mounted on the shipping frame 310 may be a fan blade storage container 370 which enables the fan blades of the fan section to be stored and transported on the shipping frame.
- the fan section F When initially loaded on the shipping frame 310, the fan section F is in an upright or vertical transport position. Because of the size of the cargo doors on some aircraft, such as a C130 cargo aircraft, it may be necessary to tilt or tip the fan section ninety degrees (90°) in order that it may be loaded on the aircraft and transported. Accordingly, the shipping frame 310 may be tilted or tipped such that the fan section F is placed in a horizontal position.
- the fan dolly 10 has mounted upon it the fan section F of a jet aircraft engine.
- the fan dolly comprises a frame assembly 12 which includes a plurality of cross members 16 which are attached in a perpendicular fashion to longitudinal members 18.
- the combination of the cross members 16 and longitudinal members 18 resemble an H frame configuration.
- the ends of each cross member 16 are upturned at a specified angle A.
- Attached to the upturned end portions of cross members 16 are pylons 14.
- Pylons 14 serve as base supports for the fan dolly 10 wherein there is a clearance between the ground level and cross members 16.
- Mounted on cross members 16 and pylons 14 are a pair of rail members 20 which extend substantially parallel with longitudinal members 18.
- the attachment of the foregoing structural elements may be achieved as by welding, or by an appropriate nut and bolt combination.

- the free ends of rigid extensions 26 include joints 28 which in turn connect to moveable extensions 30.
- the free ends of moveable extensions 30 include pintles 32 which may be attached to the hitch of a vehicle for towing the fan dolly 10.
- the hinges 28 enable the fan dolly to be towed by different types of vehicles which may have trailer hitches which are positioned at different heights.
- Caster assemblies 40 serve the dual purpose of providing not only locomotive capability to fan dolly 10, but also enable the fan dolly to be positioned at the appropriate height when the fan dolly is engaged with the shipping stand 210, shipping frame 310, or a fan section which has not been removed from an aircraft.
- Caster assemblies 40 may be attached as by attachment flanges 42 to pylons 14.
- the lower end of each assembly 40 includes a wheel or caster 44.
- the height of the fan dolly is controlled by means of jacks 46 and corresponding hand cranks 48 which raise or lower the corresponding wheel 44.
- Each of the hand cranks 48 are synchronized with one another such that the same degree of rotation of each hand crank results in the same vertical displacement of wheels 44.
- each fan support assembly 60 includes a pair of vertically extending stanchions 62.
- Stanchions 62 may be mounted on train assemblies 120 via base flanges 63 as by a nut and bolt combination or as by welding.
- Stanchions 62 may be rotatably pinned to base flanges 63 which enables the stanchions 62 to be positioned horizontally for storage or transport of the fan dolly when not carrying a loaded aircraft engine component.
- cross members 64 are provided which attach to stanchions 62.
- Stabilizers 66 cooperate with attachment rods 102, as will be further discussed below.

- a cable ratchet assembly 80 is connected to each of the stanchions 62 adjacent the locations of stabilizers 66.
- Each ratchet assembly 80 includes a ratchet mechanism 82 that controls the length of corresponding cable 86 which extends from the ratchet mechanism 82. Control of cable 86 is achieved by a hand crank 84 which cooperates with the ratchet mechanism 82.
- ratchet mechanism 82 allows the length of cable 86 to be shortened or lengthened wherein a locking device within ratchet mechanism 82 locks the cables 86 when positioned at the desired length. Cables 86 are routed over rollers 88 and the free ends are available for attachment to securing rings 90.
- Securing rings 90 enable dynamometers 96 to be secured to each corresponding cable 86.

- Attached to the opposite end of rod 102 is an aft ground handling flange 106.
- Ground handling flange 106 is designed to mate with a matching ground handling pad on the fan section F.
- flange 106 mates with ground handling pad 107.
- A-shaped ground handling flange 104 attaches to the fan section F by aligning the bolt holes 108 of ground handling flange 104 with the bolt holes 109 of attaching ring 110 and then placing a securing pin or bolt through the aligned holes.
- fan section F is safely secured to the fan dolly wherein the fan section is suspended between the stanchions 62.
- a clearance exists between the peripheral edge of fan section F and cross member 16 such that the only points of contact between the fan section F and fan dolly are the ground handling flanges 104 and 106.
- stabilizers 66 are used to ensure that the fan section F does not rock or sway horizontally between stanchions 62.
- stabilizers 66 are not load bearing members, but are simply used to stabilize any possible swaying or traversing movement of fan section F. Since stabilizers 66 have adjustment slots 68, different size fan sections F may be secured by the fan dolly of this invention.

- gaps exist between upper flanges 254 and lower flanges 256. Conveniently, these gaps correspond to the height of aft spacers 260 and forward spacers 261 which enables spacers 260 and 261 to be placed in the gaps.
- aft mode assembly 242 and forward mode assembly 244 differ in the number of stabilizing webs 250 and 252, and corresponding lengths of stabilizing flanges 254 and 256.
- forward spacer 261 is of a rectangular cross section and includes a truck mode transport slot 263 formed on an exterior edge thereof. Forward spacer 261 further includes an air mode transport slot 282. A plurality of alignment holes 265 are formed through the forward spacer and which cooperate with a corresponding plurality of spacer retaining bolts 266, as shown in Figures 21a and 21b, as will be discussed further below.

- pistons 269 are concentrically mounted within cylinders 268 to form common hydraulic lift devices or lifting mechanisms.
- cradle assembly 224 may be lifted by means of pistons 269 which contact the lower surfaces of longitudinal supports 226 and which are activated by the control of hydraulic fluid from a hydraulic pump (not shown).
- the cradle assembly 224 is raised to a specified height which enables spacers 260 and 261 to be inserted in the gaps between flanges 254 and 256. Once the spacers are securely in place, hydraulic pressure within cylinders 268 and pistons 269 are relieved which transfers the load of the loaded jet aircraft engine onto the respective shock absorbers 274.
- the lifting mechanisms When it is desired to lower the cradle assembly 224 for placing the shipping stand 210 in the air transport mode, the lifting mechanisms are activated, spacers 260 and 261 are removed, and cradle assembly 224 is lowered by controlling the movement of pistons 269 in a reverse direction.
- the lifting mechanisms of this invention are described as hydraulic lifting devices, it will be understood that other suitable lifting mechanisms may be used such as mechanical scissor jacks or the like.
- shock absorbers 242 achieve the function of shock absorption by positioning them between the frame assembly 211 and cradle assembly 224.
- each shock absorber 274 operatively connects storage support bracket 272 of the frame assembly 211 to transport bracket 271 of the cradle assembly 224.

- fan section F In operation, once the fan section F is removed from the core section C and secured to the fan dolly 10, and the inlet cowl I is separated from the fan section F, the fan section F may be loaded on the fan shipping frame 310. As shown in Figures 28, 29 and 29a, fan dolly 10 is coupled with fan shipping frame 310 by means of male connecting members 323 forming a compression-type fitting connection.
- fan section F may be transferred onto shipping frame 310 by manipulating wheels 156 of train assemblies 120 or by simply pushing the fan section F when the train assembly 120 is disengaged to cause train assemblies 120 to displace along rail members 20 and then onto rail members 322.
- the stanchion stabilizers 336 Prior to the transfer of the fan section F onto the shipping frame 310, the stanchion stabilizers 336 must be removed since they are mounted on rail members 322.
- the fan section F is then in a position for securing it to the shipping frame by aligning the template 332 with attaching ring 110 and placing bolts or securing pins (not shown) through the aligned holes 109 and 333.
- brackets 104 and 106 may be disengaged from the fan section F, and train assemblies 120 may be displaced back across the shipping frame 310 onto fan dolly 10. Then fan shipping frame 310 may be separated from the fan dolly 10 resulting in the fan section F being fully supported solely by the shipping frame 310.
- stanchion stabilizers 336 are repositioned on rail members 322 and stanchion attachment brackets 338 are connected to ground handling pads 107.
- the shipping frame is prepared for rotation to the horizontal transport position if it is necessary to transport the fan section F on an aircraft such as a C130.
- the rotating or tipping operation commences with deployment of the platform assembly 340.
- a pair of opposing chain hoists 345 and 346 with corresponding handles 347 and 348 are secured to the shipping frame and platform locks 349 may then be unlocked.
- Chain hoist 345 is secured between template bracket 334 and longitudinal bar 342 by means of a cable or chain 352 which attaches at opposing ends to platform retaining eye 350 and anchor point 353.
- the other chain hoist 346 is secured between longitudinal member 314 and rail member 322 by means of cable or chain 356 which attaches at opposing ends to frame retaining eye 354 and anchor point 357.
- Hand crank 347 of chain hoist 345 is manipulated to lower the platform assembly by means of corresponding chain 352. Hand crank 347 is manipulated until the platform assembly 340 rests on the ground.
- caster assemblies 360 have been removed from the shipping frame 310. In most circumstances, it is desirable to remove the caster assemblies because, during the tipping operation, it is necessary that the shipping frame be in a completely stable and stationary position.
- fan section F may be rotated or tipped to the horizontal transport position.
- chain hoist 346 is manipulated by hand crank 348 to enable the deployment of chain 356 which, in turn, enables the fan section F to be tipped onto platform 342.
- Hinge mechanism 386 enables the fan section F to rotate from the vertical position to the horizontal position.
- a support bar (not shown) may be placed inside each longitudinal member 314 and slidable into the abutted longitudinal bar 342 when the fan section F is tipped.
- a longitudinal slot 358 may be formed in each longitudinal member 314 wherein a handle 359 attached to the support bar enables manipulation of the support bar into and out of longitudinal bar 342.
- the support bar may be inserted into longitudinal bar 342 so that approximately one-half of the support bar is positionable in both the longitudinal bar 342 and longitudinal member 314.
- the fan section F is tipped completely to the horizontal position.
- hand crank 348 is again manipulated to draw in chain 356.
- latch mechanisms (not shown) are activated to securely lock the frame assembly 312 in place.
- caster assemblies 360 may be reattached to the pylons 320 located on platform assembly 340 enabling the fan section F to be transported in the horizontal position.
- loading indicating devices such as dynamometers (not shown) may be placed in-line between the ends of chains 352 and 356 and their respective retaining eyes 350 and 354. This load indication ensures that one particular chain hoist is not under or overloaded which in turn ensures that there is a smooth rotation of the fan section F from the vertical to the horizontal or vice versa.
- FIGS 33 and 36 are elevational views which only show one side of the apparatus, it will be understood that hoists 345 and 346 are each deployed in pairs, each pair positioned on opposing lateral sides of the shipping frame. Thus, four chain hoists may be used to tip the fan section F. Although chain hoists are illustrated in the preferred embodiment, it will be understood that other types of securing devices may be used such as ratchets or locking pulley systems.
